[structure: see text]. A new asymmetric totalsynthesis of (+)-eremantholide A is reported in which a Hoveyda-Grubbs ring-closing metathesis (RCM) reaction is used to assemble the nine-membered oxonin ring, and an enolate alkylation between the 3(2H)-furanone 2 and O-triflate 3 is exploited for C(9)-C(10) bond construction. An Evans asymmetric aldol reaction and a Sharpless asymmetric epoxidation served
